That is, the water within an eddy usually has different temperature and salinity characteristics to the water outside the eddy. There is a direct link between the water mass properties of an eddy and its rotation.
Mode-water eddies have a complex density structure. Due to their shape, they cannot be distinguished from regular anticyclones in an eddy-centric (focused on the core of the eddy) analysis based on sea level height. Nonetheless, eddy pumping induced vertical motion in the euphotic zone of mode-water eddies is comparable to cyclones.
In fluid dynamics, eddy diffusion, eddy dispersion, or turbulent diffusion is a process by which fluid substances mix together due to eddy motion. These eddies can vary widely in size, from subtropical ocean gyres down to the small Kolmogorov microscales , and occur as a result of turbulence (or turbulent flow).
A warm core ring is a type of mesoscale eddy which forms and breaks off from an ocean current, such as the Gulf Stream or the Kuroshio Current.The ring is an independent circulatory system of warm water that can persist for several months before losing its distinctive identity. [1]
The governing forces of an eddy are very dependent on its size. Small eddies are largely governed by viscosity and direction of the flow of a water body. [2] However larger eddies are formed from a balance between the horizontal pressure gradient force, arising from differences in densities of the meeting water masses, and the Coriolis force. [4]
A second bloom can occur once the eddy has moved closer to the deep ocean, when the outer reaches of the eddy can gather nutrient-rich water from either the coast or from an adjacent eddy. Coastal water transported by this outer ring advection can move from the coast into the eddy in six days which also allows for the rapid transport of coastal ...

The eddy covariance (also known as eddy correlation and eddy flux) is a key atmospheric measurement technique to measure and calculate vertical turbulent fluxes within atmospheric boundary layers. The method analyses high-frequency wind and scalar atmospheric data series, gas, energy, and momentum, [ 1 ] which yields values of fluxes of these ...
